While the TCG intermediates are architecture neutral there are enough
difference between the various guest architectures in the way exceptions
are raised
Oh whoa, I thought I could have an architecture neutral way to interface
with the TCG to find this out.
Yes, I do have to use the decode tree, and converting the script to output
the codes would suffice for my case. However, I do not know how to do that
at the moment. I've tried my best to

Which
I need to determine the set of instruction encodings that the TCG can
support for a given platform. I am not bothered whether the target runs at
all, and in fact it is better if it doesn't, so runtime or translate time
doesn't bother me.
Imagine I were adding support for more instructions for a

That I know of, the TCG plugins do not allow me to feed the QEMU instance
dynamically changing opcodes. I wouldn't use TranslatorOps if I don't have
to. I want to facilitate a use case in which the contents of the target
being emulated are changing, but it is not a self modifying target. I have
to

Hello,
I would like to be able to, from the linux-user/main.c, access the target's
registered TranslatorOps instance. How would I do that when 1) the TCG is
correctly initialized and ready to run 2) before QEMU starts to run or when
it is safely paused?
